You could make the argument that if all of the capital in crypto only had to be spread across 50 coins that that would make each of those coins extremely more valuable. In light of that thought, is the huge variety of Altcoins ultimately a good or bad thing for crypto?
This is bad, because as stated, the demand and value of others is reduced. it is better to leave the top and most current coins on all stock exchanges as before, and to dry all the rest.
